SPECIFICATION forming part of Letters Patent No. 652,552, dated J' une 26, 1900. Application filed Tune 3,1899. Serial No. 719,192. (No model.)

To @Zi whom it may concern,.-

Be it known that I, ISAAC N.. THOMAS, acitizen of the United States, residing at'Lima, Allen county,Ohio,have in vented certain new and useful Improvements in Washing-Machines, of which the following'is a specication.

My invention relates to and its object is to provide a cheap and efficient washing apparatus which may be applied to the common Washtub in general use. This object is attained by means of the devices and arrangement of parts hereinafter described, vand shown and illustrated in the accompanying drawings, made part hereof, in which--A Figure lis a top plan view of the pounders, hereinafter referred to, detached; Fig; 2, a central vertical elevation of my device, partly in section; and Fig. 3, a side elevation of my machine seen at a right angle to the point ofV view in Fig. 2.

Like numerals of reference indicate like parts throughout the drawings.

In the drawings, 1 is a washtub.

2 is a stoutv board or plank of sufficient length to rest with its ends upon the upper margin of the tub. Across the middle of the plank is an upright housing 3. Through the housing and through the plank, in vertical alinement, are holes 4, in which slides ver. tically a staff 5, the holes 4 serving as guides for the stali". Included in and servin g as part of the staff is a stirrup 6, having an opening therethrough in the'direction of the length of vthe plank'2. Through the stirrup 6 passes a lever 7, which by means of pin 8 is pivoted to the stirrup. At one end of the plank is a vertical bar 9, pivoted at bottom, as at 10, tothe plank and nivotally connected at top, as at 1l,`

to the lever 7.

Near to the bottom of the staff 5 are secured I two bars, which cross each other at right'an'-v gles. Beneath the Outer extremity of each of these cross-bars and at the point where they 'cross 'each other isa pounder. Each of these at bottom and have Openingsmherethrough near. their top. The outer vesselsl are open only at bottom, as indicated in section in Fig. 2. Resting upon and secured tO` the Yfour cross-arms is `a circular rack or ratchet,` having for its center the staff 5. Pivotally secured to the under side of Vthe plank 2, as at 18, is a pawl 19, having a stop 20. The pawl hangs normally directly above the ratchet 17. It is obvious that the arrangementof the pawl and ratchet may be varied without departing from my invention provided their action is at the end of the upstroke of the staif and its load.

It is designed that the cross-bars l2 and the pounders secured thereto shall be revoluble horizontally. This may be accomplished either by mounting the cross-bars loose horizontally upon the staff or by vrsecuring-the cross-arms rigidly to the staff and suspending the lower part of the stafh from the stirrup 6,`as at 6a.

The Operation of my device is as follows: Assuming that the plank 2 is in place, with its ends upon the top of the tub, and that there are in vthe tub water and the vclothes to be washed, the Operatorlifts the lever 7, which carries with it the five pounders. At the upper end of the stroke the circular ratchet comes in contact with the pawl, and as the lever is raised still farther the pawl pushing upon the rack causes the cross-bars carrying the pounders to swing horizontally. Thus at each upward vstroke the series of pounders are caused to describe a small part of a revoluftion, so that the pounders will at each downstroke fall in a new spot, thus insuring the distribution of the action of the pounders over the entire surface of the clothing. As the pounders press upon the wet fabric the airis forced into and through the same by the funnelshaped shells 13 14 15, the water furnishing a seal for the bottoms thereof. When the series of pounders is lifted, the moment the shell 15 rises above the surface of the water the seal and vacuum in the vessels 14 and 15 are broken, and now thepounders may be lifted with but little resistance.

Having described my invention, what I claim, and desire to secure by Letters Paten t, 1s-
